Perhaps I should read Ursula's bag theory myself, because I'm not quite following how it applies to Solarpunk or talking about climate from this.
I like everything I've read of Le Guin. Just finished reading her last one, Lavinia (Pre-Roman historical myth based on the Aeneid). The Dispossessed is great and you get a feel for an anarchist society. She also wrote a good translation of the Tao te Ching.
